Netflix is the only current service delivering 4k, with Amazon testing delivery. The trouble with it is the same as HD, though: a HD stream can be 10Kbps. The specification is useless: what counts is the lowest point of the data rate between source and viewer.

You can create a button from http://www.amazon.com/gp/sendtokindle/developers/button . If you like further qs about it you can send it to me so I will be happy to assist you.
By the way for ipad I advice you to send it to instapaper and evernote which is frequently used apps for reading.

Creativity is the phrase that comes to mind when I think about Atif. I’ve had the pleasure of knowing him for the last 25 years as a friend. Above all, I was impressed with Atif’s ability to absorb new technologies. And, of course, his dignity. Atif would be a true asset for any positions requiring team leading and project management, and comes with my heartfelt recommendation.

I met Atif when he was with the Demsa Group. His engaged and profound knowledge of both digital marketing and social media tools, provides for a unique and proficient profile. In addition, he is a great networker and has an enthusiastic personality, which is always welcome in a corporate environment. I could work with Atif again with great pleasure.

I have known Atif for about 15 years, and during that time I have used his services a number of times. Each time he delivered what we asked of him, did it with creativity, did it on time, and stood behind his work with great follow-up. Today, Atif has grown to become an expert in many matters that have to do with MIS and integrated IT systems that provide businesses with secure, and robust information systems, - on and off-line . Atif is an active speaker, and a much sought after expert that stays abreast of the latest developments in a very rapidly evolving field. I highly recommend Atif as a senior executive, a valuable consultant, and a hands on builder/creator.

Atif has always been a very valuable sounding board for developments in the IPTV sector in Turkey and beyond and has provided great advice based on his extensive experience to both myself and my colleagues.

Atıf Unaldı is not only an expert in his field but also a very considerate and creative professional who loves his job and who works professionally with an amateur spirit. He takes his job very seriously, suggests and orients you in the right direction and is open to debates and criticisms. I recommend him highly if you need to work with someone who has a creative mind and a sensitive personality.
